Question from George: How many cubic feet in a cubic yard? |
George,
A cubic yard is a yard cubed. So
(1 yard )3 = 13 yard3 = 1 yard3 = 1 cubic yard .
Since 1 yard = 3 feet, we have
1 cubic yard = (1 yard)3 = (3 feet)3 = 33 feet3 = 27 cubic feet.
Simply put, when dealing with square or cubic units, you square or cube the appropriate conversion factor.
Cheers,
Stephen La Rocque.
